i l Application filed4 July 11, 1883. (Xo model.)v

` I Tol all whom, t may concern.:

Beit known that l, Pnrnnfis CHANEY, Jr., of Brooklyn, in Kings county, and the State of New York, have invented a certain new and 5 useful Improvement inl Dust-Collectors, of

which the following is a specification.

This improvement will be described in de- Ytail, and then pointed out in the claims.

In the accompanying drawings, Figure l is io' a transverse Vertical section of a dust-collect or embodyingmy improvement. Fig. 2 is a central vertical section thereof, t-aken in a plane at right angles to that of Fig. l. Fig. 3` is a View of one of the standards, whereby r 5 a rotary separator,I forming a part of the dustcollector, is supported, and cut-off appliances l used' in connection with said standard, the same being seen from the plane indicated by the line a: a", Fig. Fig. L is an edge View 2o of a ring whereby a circular packing whichr is employed 'in the machine is supported.`

fr Fig: is aperspectiye View of one ofthe chambers of a rotary separator. Fig. 6 is an exterior View of 4a portion of one side of the dustcollector, illustrating the mechanism for imparting a rot-ary motion to the separator, and Fig. 'E' is aVertica-l section corresponding to Fig. 2, but on a larger scale, showing one end portion ofthe separator, a standard supporting the saine, and parts adjacent thereto. f

Similar letters of reference designate corresponding parts in all ythe iigures.

A designates the rotary separator of the dust-collector. lt consists, essentially, of a number of chambers, a, which are made separate and independent oi' one another, and are fitted together radially and ,occupy positions between frames Z1 c. Each of the chambers a'. 4o consists of end pieces, 1, connected near the extremities by longitudinal rails 2 3. Stretchers '4 extend between the rails 2 3 at about the l'middle of their length. They are affixed to f the rails 2, and have interposed between them 4 5' and the rails 3 cushions 5, of india-rubber or rother resilient material. Pairs of rods 6 eX- `tend between the end pieces, and they may jextend through the stretchers. In' the end t Apieces' are openings 7. In one of the side 5c` edges of each end piece is a groove, 8, and at l the other side edge thereof is a tongue, 9. It ,will be observed that the end pieces taper longitudinally. The taper is such that the end bers.

pieces of the whole series of chambers c may be fitted together in the form of a circle with their tongues and grooves interinatched. The various parts of the frames of the chambers a may be made of wood, with the exception of the cushions 5 and the rods 6. i The latter will lpreferably be made of metal; but eren vthey 6o may be made of wood. Cotton or linen cloth or other suitable fabric is wrapped around the rails 2 3 and rods 6 of the chamber a, and is united by sewing or by tacking its ends to one y of the'said rails. It will also be tacked to the 6 5 end pieces. It will be seen that each of the chambers a is complete initself and independent of the others, andthat unobstructed spaces are left between the sides of adjacent cha1nbers, so that air may pass diametrically across `7o the.'separator.

The frames b are of circular form, with iangcs at the front. They are supported by spiders b', which are rigidly affixed to a shaft,

B, so as to turn therewith. This shaft is sup- 7 5 ported in bearings B', which are fastened Vto the walls/d of the housing of the dust-collector. The frames c are circular in form, and extend around the outer sides or faces of the end pieces of the chambers a, near the wider 8o extremities. Nails or screws c pass through these frames c into the end pieces of the chambers u, and thereby secure the chambers in place.

Outside the ends of the separa-tor are educ- 8 5 tion-chambers C. These eductionchambers C consist of pieces of sheet-iron or other suit# able material, e, bent into circular form, eX- tending from the walls (Z of the housing' inwardly toward the ends of the separator A. These pieces e extend close to the end pieces of the chambers a, near their outer extremities. Their inner edges are fastened to the inner peripheries of circular ribs f. Theseribs are secured to walls d. In the upper part of the pices e are openings c', through which 'communication is afforded between the eduction-chambers and passages C, that lead to the central part of a suction fan-blower, D.

All the openings 7 of the chambers a, except loo such as are cutoff in a manner and for a purpose which will be hereinafter explained, are Y in communication with these eduction-cham- Packings, consisting of bands of india` rubber, leather, or like material, g, are fastened by nails or screws to the outer Vextremities of the enldpieces of the chambers a, and extend l tops of the rails ofthe lowersections. The

between therwalls d and the pieces c, forming part of the eduction-chambers.

Between the eduction-chambers and' surrounding the separator A circumferentially is .a receiving-chamber, E, into which is discharged the air from which dust, consisting of iiour or other valuable material, is to be collected. The packings g prevent leakage of air from the receiving-chamber into the eduction-chambers without passing through the separator. Packings h, consistingof bands of india-rubber, leather, or'other suitable Inaterial, are fitted against the inner peripheries of the frames b, and extend outwardly beyond the same into groovesjz' in the standards of cutoffs L. Metal bands j, fastened at the ends by screw-bolts, are expanded within these packings to hold them against the frames b. The upper portions of the cut-off standards are circular, but their lower portions have diverging sides, fitted with packings k of india-rubber, leather, or other suitable material, adapted to impinge against the end pieces of the chambers a of the separator A. These packings k are so arranged that the end pieces of three adjacent pieces, a, of the separator may be rotated'into a position opposite the 'space which is between the packings.- The standards of out the use of the packings h.

the cut-offs fit the shaft B. They also extend to and are secured in contact with the pieces e of the eduction-chambers G. The packings 7L prevent leakage of air between the eductionchambers O and the space encircled by the chambers a of the separator A. Obviously, if blocks of wood were fitted to the spiders b' of the separator to close the spaces between their arms, this object could be attained withrlhe packings 7c cutoff communication between the eduetionchambers C and the openings 7 in the end pieces of those chambers a which are opposite the space which is boundedby these packings.

The manner of combining the packings gh k'withl the parts to lwhich they arev applied may be best seen in Fig. 7 but is also shown in Figs. 2 and 3.

The dust-laden air is discharged into the chambers E through ducts E2, from forceblowers E3, 'portions of which are shown in Fig. I, and which may be of any suitable construction. The dust-laden air thence passes from the antechambers F/ to the receiving-chamber E. These antechambers E are separated from the receiving-chamber Eby lattices F. When the dust-laden air strikes these lattices, it is divided into numerous currents, which are deiiected downwardly, and at the same time checked to such an extent that the heavier particles of dust fall by gravity into collecting-chambers G. The lattices have removable sections '1,

which may be removed to afford access to the chambers cc of the separator A. The inner sides of the upright rails of the removable lattice-sections Z may rest against shoulders, "and the bottoms of said rails may rest on the removable sections Zwill then be held in place by gravity. By removing the pins which secure any one of the chambers to the frames c, and detaching the packings g therefrom,

ying-chamber I. rlhis main collecting-chamber Ihas at the bottom a spout, I. The main collecting chamber I has fitted in slideways in a mouth-piece with which it is provided a number of knockers, J. But two vare here shown, although any desirable number may be employed. The mouth-piece of the main collecting-chamber I is wide enough for three of the chambers a of the separator to occupy a position over it at one time. Vhen any three of thesev chambers are over it, the openings 7 in their end pieces are cutoff by the cut-off packings lc from communication with the eduction-chambers C. The knockers J l are retracted from the chambers c, vwhich are thus cut off by eccentrics or cams Jl on a rotary shaft, J 2, and are impelled against these chambers by springs J. The springs Jsare supported at their adjacent ends in a stationary standard, and atl the outer ends theyare connected to screw-boltso, whereby the force with which they actuate the knockers may be varied. j

At thel top of the collectingchamber I are strips of packing p, madey of india-rubber, leather, or other suitablematerial, and -inside the mouth-piece of this chamber are similar packings, p. These packings p p extend to the separator and prevent leakage of air between the parts on which the packings are arranged and the separator.

The mechanismfor imparting rotary motion to the separator and to the gates H is shown in Figs. '2 and 6, and in dotted outlines in Fig. 1. l

On the shaft B is rigidly affixed .a ratchetwheel, K, on which acts'a pawl, K', that is loosely pivoted to a crank-wrist, K2, extending from a wheel or pulley, K3. The periph- IOO ery of the wheel or pulley K3 is provided with sprocket-teeth, with which engages a chain, Kt, and said wheel K3 is supported on a fixed stud projecting from the side of the machine. The chain K4 also engages with a sprocketwheel, K, which is mounted 011 the shaft J2. The shaft J 2 is provided with a pulley, J 4 on which may be iitted a belt for imparting m-otion to the shaft. Theshaft J 2 constitutes the driving-shaft of the machine. On the shaft J 2 are sprocket-'wheels J5, which receive fchains ik), f

The teethoi the ratchet-wheel K are of such number that every time the pau-'l K impels the wheel-a tooth forward three of the chambers a of the separator A, that were over the will be moved past .'themouth-piece of said chamber, and the three succeeding chambers will be rotated into aposition over the mouthpiece of the said chamber, and will be cut off by the eut-oit' packings [i: from communication The motion of the separator is intermittent, it being allowed Vhile three chambers dwell over the Amouthpiece of the main collecting-chamberI, the linoekors strike them and shake the dust from them. t vArs -these chambers are then cut off from the suction of the education-chambers the detachment of the dust through the j ar or shake produced by the knockers is facilitated. The knock er; cams are set so as to operate the knockers alternately. Some of the dust will be shaken by the action of 'the lnoclrers from other chambers, a, than those which are immediately over the mouthpiece of the main collecting-chamber I. This dust will Vfall into the chambers G, and will chamber I.

AThe separator is really between the receivtor; hence if one of the force-blowers is delivering more dust-laden air than the other, the excess of air can pass over to the side of the separator where the lesser stream of dust-laden air is being delivered.v lThe dust-laden air, before it can pass into the ednction-chambers, must pass through the-cloth of the chambers c into the space inclosed thereby, and thence throughthe openings 7 ofthe end pieces of th ese chambersintotheeduction-ehambers. In pas. ing through the cloth of the chambers c the dust The dust -which is carried on the cloth around to the mouth of the main collecting-chamber I is deposited into the said chamber by the action of the hnockers. The suction-blower is preferably rotated,' so that it will induce an outward current of air slightly in excess of the aggregate currents which are delivered by the force-blowersEa. InI the eduetion-passagcs C are slides or valves c?, whereby air may be admitted from outside the dust-collector into the eduction-passages. By adjusting these 1valves Iam enabled to so neutralize some of the action of dust-laden air delivered by the force-blowers E3 into the receiving-chamber E to pass downward between the chambers a of the separator, when they` are eut olii', to the main collectingehamber I. The dust in this current oi' air is not wasted. as it passes into the main collectinglch'aniber; In fact the passage of this current of air into the collecting-chamber without first passing through the cloth of the separater is a relief to the separator, for if this current of air passed through the separator ,the separator would have t'o do the additional work of separating the dust from it. This current of air passing between the cut-off chambers c of the separator aids in detaehing the dust therefrom, I make the suction-blower run in excess of the force-blowers and then neutralize it, because it would be impracticable to maire such a fixed relation between the ,action of the blowers as is necessary to produce the desired result, owing to the varying conditions of the dust-laden air and of the cloth of the separator. passing through the separator tends to rush to the openings bywhich communication is established between the eduotion-chambers C andthe eduction-passages C', hence the air passes to these openings at various angles. This is advantageous in that'the passage of air across the surfacesl of the cloth at different angles continually shifts the nap of the cloth and keeps kit distend'cd, so that it Vwill catch and hold alarger quantity of dust than it would otherwise. This passage of air over the cloth at different angles can best be understood by means of the fine lines a, shown on the chambers a in Fig. 2. As the tendency of the air in the chambers c is always upward, no matter inwhat position the chambers are brought by the rotation oi the separator, it follows that the direction of the air in the chambers, lwhich are at any time at the upper part of the separator, will be toward the upper and outer ends `of the openings 7 in the ends of said chambers from all parts thereof, while the direction of air in the chambers which are at the lower part of the separator will be toward the upper and inner ends `of the openings 7 in the ends 'f said'chambers; hence it is obvious that when the chambers are at the lower part of the separator the air will pass over the cloth in a `different direction from that which it will take when the chambers are at the upper part .of the separator. It will also be observed that when the chambers a are brought into horizontal positions at the sides oi' the separator the air in the chambers will pass directly to- `ward the end openings, 7, in adirection parallel with the shaft B. It will be observed thatthe air in passing through this dust collector comes in contact with the cloth of the separa- `tor but once.

The cushions 5,at the ends of the stretchers 4 inthe chambers a, prevent the knoclrers from injuring the chambers.
